SHD-SE-01 is a generic equipment, i.e. the hardware is fixed
and specific functionality (communication with individual
peripherals, their control and readout) can be achived by
application software for internal MCU only.
SHD-SE-01 board, without battery
Power supply
SHD-SE-01 is supplied from built-in primary non-removable battery and protected by 100 mA resettable fuse. Energy
consumption should be minimized by software techniques in application program. Properly designed application software
allows battery lifetime of several years. SHD-SE-01 device is permanently powered on, delivered in sleep mode.
Complete functionality of the device is controlled by application program in MCU dedicated to TR module and equipped by
IQRF OS operation system. Refer to the documentation of development set DS-SHD-SE-01. Application SW should be
uploaded wirelessly.
Sleep mode
For minimizing of current consumption, it is possible to switch off individual functions and peripherals. Thus, to achieve long
battery lifetime, individual parts should be disabled in application program as much as possible and activated just in short
periods when necessary.
An ultra compact low-power three axis linear accelerometer (motion sensor).
Real Time Clock Calendar with programmable alarm output.
16 kb EEPROM memory. Data remains stored after power off. Overwriting is not unlimited, number of erase/write cycles is
1 000 000 typically.
Temperature sensor
Temperature is measured by precise optional digital on-board sensor.
Light sensor
Illumination is measured by the phototransistor.
Functionality of the pushbutton is fully under application software control.
Functionality of the LED is fully under application software control.
IQRF transceiver module
The RF circuitry is compatible with IQRF smart transceiver TR-54DA. The only exception is implementing one LED only
(instead of two, the green LED is not used).
SHD-SE-01 includes built-in PCB antenna.
The plastic case can not be disassembled.

SHD-SE-01 is delivered with Demo software illustrating functionality of all on-board parts.
The device stays completely in sleep mode except of sending an RF packet with data acquired from all sensors and
peripherals (except of RTCC which is disabled due to power saving) whenever the button is shortly pressed. (The Demo
software is the same as for the DS-SHD-SE-01 development set but without periodic sending of packets in 64 s periods.)
This data can be received by another IQRF TR module, forwarded to PC to be displayed on the screen etc. No networking
is applied in this demo SW.
Application program should be uploaded in MCU via wireless RFPGM programming.
Refer to the documentation and source codes of development set DS-SHD-SE-01 for packet format and other details.
Response to the pushbutton and LED indication
• Short press (< 5 s, LED is on): RF packet sent
• Long press (> 5 s, LED is flashing): RFPGM mode. It can be cancelled by the pushbutton pressed for ~1 s or
automatically after ~1 min.
